The dynamics of Newton's laws

• By Tabatha Lisle

2
Magnetic force

• Magnetic force is when two magnets pull together
  or apart.
• For example if you put two south magnets
  together they wont stay together but if you put
  south and a north side they stay together.

3
Electric force

• Electric force is when you can feel the force .
• Foe example when you rub your hand really
• Fast on a cover you can touch someone and you can
  feel the electric going to the other person from
  you.

4
Gravitational force

• Gravitational force is a force that holds objects
  down.
• For example gravitational force is what holds us
  down.

5
Weak interaction and nuclear force

• It is rare because it is only found in the
  nucleus
• For example an explosion

6
Newton's first law of motion

• Newton's first law of motion is that an object
  in rest stays in rest and an object in motion
  stays in motion.
• For example a toy ball rolling across the floor
  and doesn't stop, it will continue to be in
  motion until it hits something or anther force
  stops it.

7
Newton's second law of motion

• When someone applies force to an object it will
  accelerate.
• For example pushing a box across the room

8
Newton's third law of motion

• Every object has an equal and opposite
  reaction
• For example a rocket . A rocket would be one
  because the fire lifts it up and pushes against
  the ground causing it to have a reaction.

9
FM x A

• An example would be a plane crashing
• You will need to know the force of the plane
  because you wouldnt want the plane to crash
  again.
• You will need to know the mass times acceleration
  to figure out the force of the plane

10
Mf/a

• An example of mf/a would be a car
• You have to know the force of the car and the
  acceleration to get the mass.

11
Af/m

• For example a fish swimming
• To know the acceleration of the fish you have to
  know its force and the mass of the fish.

12
Wm x g

• for example a rock
• To know the weight of the rock you have to know
  the mass and the gravity.

13
Mw/g

• For example a building
• You have to divide the weight of the building by
  the gravity.

14
Gw/m

• For example a dog
• You have to know the weight and the mass of the
  dog to know how much gravity is pulling it down.
